Abstract: REQUEST FORWARDING SYSTEM                  ABSTRACT OF THE DISCLOSURE    Storage access requests are forwarded from plural input/output channels to shared main storage.  An address word in each request designates the identity of the source channel (CHID) and "destination" address (of a doubleword space in storage relative to which one, two or four "data" words shall be transferred).  EOT tag signal provides demar-cation of requests and also uniquely identifies "l-wide" input (Store) requests.  Quadword (QW) tag, presented with "4-wide" requests, enables the storage access system to use a single address in the request to locate two contiguous doubleword spaces in storage.  Data tags (Dl, D2), presented on a selective basis enable the access system to selectively steer (reorder the positions of) data words in an input request relative to word halves of the addressed space.  Consequently the data repositioning function associated with Read Backward operations does not require reordering of data words in the channel buffers (saving handling time and expense of "steering" circuits in the individual channels).  In association with a "l-wide" input request a single data tag, Dl or D2, is used to steer the single data word of the request into either half of the addressed space on a selective basis.

Abstract: TITLE                     PUNCH PRESS FEEDING APPARATUS                        ABSTRACT OF THE DISCLOSURE           An input shaft is drivingly connected to a crankshaft of a punch press for rotation at a preselected speed.  A geared cam drive drivingly connects the input shaft to a driven feed roll so that continuous rotation of the input shaft is converted to intermittent rotation of the feed roll.  The intermittent rotation of the feed roll is timed with the punching operation so that the feed roll intermittently advances a preselected length of stock material to the punch press after each punching operation.  Bevel gears drivingly connect the input shaft to a pull roll that rotates to continuously unreel stock material from a coil.  During the punching operation, rotation of the feed roll is interrupted forming a loop in the stock material between the pull roll and the feed roll.  At the end of each punching operation the material forming the loop is fed by the feed roll to the punch press so that the stock material between the pull roll and the feed roll moves from a loop to a hori-zontal position to insure feeding the same length of material to the punch press for each cycle of operation.

Abstract: ABSTRACT OF THE DISCLOSURE   In a blast furnace tuyere, operating at subsonic velocity, an inner cylindrical air conduit is reduced to a frusto-conical conduit near the tuyere nose.  A water cooled pear-shaped, hollow body within the tuyere is held suspended by a bracket, in a centered position, where it exerts minimum inter-ference with the pressurized fluid flowing partly through it and partly around it, having a cylindrical smaller conduit in such body and an annulus between the outer perimeter of such body and the inner wall of the cylindrical or conical conduit of the tuyere. The bracket slides parallel to the tuyere axis in guides, which are integral parts of the tuyere proper, thereby securing a centered position whenever the bracket is approaching to or retreating from the tuyere nose. The area of the annulus is uniformly decreasing when the body on the bracket is-moving toward the tuyere's nose; consequently, the air jet velocity through the tuyere is increased but by virtue of the diverging-converging inverse annular nozzle between the frusto-conical conduit and the pear-shaped suspended body, a near paralled air current with optimum thrust can be maintained at any position of the body. A driving mechanism serves to actuate the movement of the bracket and body; the driving mechanism being externally mounted at an accessible location.

Abstract: ABSTRACT OF THE DISCLOSURE         Television apparatus for producing signals for display-ing simultaneously a succession of time-separated images of an object moving in an otherwise static scene, control is provided for causing a limited number of decaying stroboscopic images of successive positions of a moving object to appear behind the image representing the latest position of the moving object including a reference field for storing video representing a scene at the start of an action cycle, a comparator for comparing picture elements of selected subsequently arriving television fields with corresponding picture elements of the stored reference field, and means for tagging and string those picture elements of the selected subsequently arriving fields shown by the comparison to be measurably different from corresponding picture elements in the reference field.  However, whereas the action cycle of the previous systems is terminated by the operator, at which time there is provided a video signal for display representing the substantially static scene with the substitution therein of those picture elements stored during the selected time period, in the present system the action is live and continuous, with a preselect-ed amplitude proportion of the tagged picture elements mixed with a complementary amplitude proportion of the real time video, thereby to cause the tagged picture elements to decay in ampli-tude at a selectable rate.  The system operates in a recursive mode thereby to cause earlier images of the moving object each to decay by a predetermined amount with each sampled mix of a sub-sequently arriving field and the stored field, and causing earlier images to decay into the background of the scene.
